钢支撑伺服系统在软土深基坑中的应用与研究

Application of Average Gap Method in Subway Tunnel Protection Area

近些年来,随着现代化城市的建设,我国软土地区基坑朝着更深更宽的方向发展,基坑变形控制成为关注重点。国内外学者对钢支撑伺服系统进行了一系列研究,验证钢支撑伺服系统能减小围护结构变形及周边环境变形,但对工程效果实际差异研究较少。对此本文依托实际工程,研究钢支撑伺服系统在软土深基坑中变形控制效果,总结具体变形控制范围,为类似工程提供参考。

In recent years,with the construction of modern cities,foundation pits in soft soil areas in our country have developed deeper and wider,and foundation pit deformation control has become the focus of attention.Scholars at home and abroad have conducted a series of studies on the steel support servo system,verifying that the steel support servo system can reduce the deformation of the enclosure structure and the surrounding environment,but there is little research on the actual difference of the engineering effect.Relying on actual engineering,this article studies the deformation control effect of the steel support servo system in soft soil deep foundation pits,summarizes the specific deformation control range and provides references for similar projects.
